Extracted text: "Color fastness to wash" of a colored textile fabric is defined to be the fabric's resistance to changes in color when subjected to repeated washing of the fabric. The test for ensuring the fastness of colored fabrics is performed in a dying lab. A newly manufactured lot of a red multifiber fabric baseline color measurement of each swatch. The 10 swatches undergo 10 identical washes, after which the color of each swatch is again measured by the same spectrophotometer. This procedure was repeated after 25 washes and again after 50 washes of the 10 swatches. sent to a dying lab for a wash fastness test. Ten swatches of the fabric are cut, each measuring 40 by 100 millimeters. A spectrophotometer is used to obtain a precise Which of the following is a true statement regarding this study? O This study uses independent groups to compare the color of the fabric at three points in time. O This is an observational study. O This is a repeated measures design that examines the change in color over time. O This is a repeated measures design using three treatments and a control. Need Help? Read It
